Application filed March 10, 1919. Serial lilo. fttllftm.

To all whom it may concern:

Be it known that we, HARRY Vnnnau and ihLltRED 1t. Gnon'rz, citizens of the United screens in which the advertisements, instead of being projected upon the screen as usual, are displayed ad acent the sides of the screen.

In this manner the use of the screen for eahibitinp; motion pictures need never be in-- tcrrupted and the advertisements are in full view of the audience during the entire exhibition with an assurance that at least a majority of the persons in the audience will, at some time before the leave, read the advertisement. The mom ers of the audieime may look at the advertisement at their own conveniem-c,and, since the display of the pictures is not interrupted to display ad vertisements, the persons composing the au-- dience Will not get the unfavorable impression which is at present produced by having the advertisements iorccd upon them to the exclusion of the pictures during the time that thc advertisements are projected upon the screen. .Another object is to provide advertising; slides which may be cheaply and readily changed as often as it is de sired to display new advertisements.

v The full ob ects and advantages of our invention Will appear in connection with the detailed descriptlon and the novel features embodied in our inventive idea are particularly pointed out in the claim,

ltefcrringnto the drawings,-

Figure l is a view in perspective of a slide holder and a portion of a motion pic ture screen. Fig. 2 is a detail View of a portion of a slide holder. Fig, 3 is an inside front view of one ot the slide supports. Fig. 4. is an end view of one of the slide supports. Fig. ti is a view of one ot the glass slides. Fig. 6 is a view of one of the advertising sheets.

Referring to the construction shown in the drawings, 10. designates a portion of a H10- tion picture screen, at each side otiwhich are placed advertising slide holders which are alike in all respects and hence it is necestion 22.

sary to describe and illustrate only one of them. The slide-holder comprises a semicylindrical member 12, preferably of sheet metal, curved into the proper shape and pro vided with a suitable reflecting surface on the inside, as hy a coating" of white paint' The top and bottom of the holder at thetront are provided respectively with down-- turned and upturned flanges 14: and 16, and intermediate these flanges the front vertical edges are connected by a plurality of T- shaped slide supports 18, each oi which has a vertical portion 20 and a horizontal There are preferably nine of these slide supports, as shown, so that ten conipartuients are provided, and back of these. 'coinpartlneins are a plurality of lamps 24,

such as incandescent electric lamps, PFC-BT81 ably one for each compartment and arranged centrally thereof at the rear. however, that the number of compartments and lamps may be varied, as desired. The slides which are employed we consider an essential feature of our invention. Each of these slides is composed of two separate plates 26 of glass or other transparent material, a sheet of paper 28, or similar mate rial, being placed between the two plates.

We have discovered that by employing two transparent plates and placing a sheet of paper, or other fabric-containing the advertisement between the two plates, the advertisement may he quickly changed and the expense is inuchless than would be the case if the letters or characters constituting the advertisement were placed directly on a glass plate. The paper may conveniently be composed or translucent material upon which is placed opaque letters, or characters to term the advertisement, but it obvious that, it desired, the letteis might be out out of a sheet of opaque paper.' in either case the lamps at the back of the slides will cause the letters to be readily visible at all times so porlit is obvious,

till

ice

that the audience may read the "advertise meut at their leisure, either while the reels are hemp; changed or after they have seen the entire program, or by looking at advertisements to rest the eyes it they become tired and any particular portion oil the picture inhibition does not prove ot' interest.

I The operation and advantages of our in Mott at a time and any advertisement may be plates together With the intermediate sheet of paper at the open end of the slide Way.

When a new sheet of paper with the desired advertising on it has been substituted for the discarded sheet the composite slide is replaced in the proper compartment. While our advertising device is intended for use particularly at'the sides of motion picture screens it is evident that it may be used in other locations.

We claim:

A11 advertising device comprising a semicylindrical caslng, inturned flanges at the top and bottom of said casing extending out beyond the vertical edges thereof, T-shaped slide supports attached to said casing extending horizontally in spaced relation between said flanges with their head portions lying in a common vertical plane with said flanges, advertising slides adapted to be inserted and held in place by said slide supports and said flanges, and a source of light located within the curved surface of said casing.

, In testimony whereof we hereunto affix our signatures.
